3k+3>12
a.k>5 or k<-3
b.k>3 or k<-5
c.k>-5 or k<3
d.k>-3 or k<5

Answer 1

Hey,
Thanks for asking this question.

3k + 3 > 12
=> 3k +3 -3 > 12 - 3
=> 3k > 9
=> 3k/3 > 9/3
=> k > 3

Since in the given options,only option (b) involves that k>3,
So the correct option is (b) that is k>3 or k<-5.


●Hope my answer helped.
